But botanists have spoken of their surprise after finding three red berries on a branch of the yew this year - in signs at least part of the male tree is becoming female.

As The Guardian reports, it's actually not all too remarkable that the tree is changing sexes. Dr. Max Coleman (of the Royal Botanical Garden) told them that yew trees have been known to change sexes, but what makes this a significant news story is that it's this tree that happens to be changing sexes.

The Fortingall Yew, another Guardian piece explains, is one of the "oldest living things in Europe," and thought to be perhaps the oldest tree in all of Britain. That's why botanists are interested, not the sex change. Only the bloggers care about the sex change part. Horny bloggers!

Many tree species contain both male and female parts (with systems to stop it pollinating itself) but some species, such as holly or yew, are usually only male or female. A few species, such as ash, routinely switch sex, producing male flowers one year and female fruits another. If a tree produces a large crop of seeds one year, it may switch the following year to male flowers to reduce the strain on itself.
